REMEDIATION
Clinoptilolite zeolite
is widely recognized as
environmentally friendly and
effective for the absorption of
toxins. In 2009, Bear River Zeolite
(BRZ? was selected by the West
Valley Demonstration Project (WVDP)
as the best performing
clinoptilolite for use in a
permeable treatment wall (PTW) to
effectively remediate strontium-90
contaminated groundwater at a closed
nuclear fuel processing plant in
West Valley, NY.
The Great Lakes
Restoration Initiative (GLRI) was
initiated through the United States
Environmental Protection Agency
(EPA) in 2010 to
protect and restore the Great Lakes.
BRZ?was selected as a stormwater
runoff filter media for multiple
studies funded by EPA/GLRI grants
based on proven performance,
low-cost, availability, and ease of
replacement.
The high cation exchange capability
of BRZ?makes it excellent for the
clean-up of oil, diesel, and
gasoline; PCBs; soluble heavy metals
including mercury, chromium; lead,
zinc, arsenic, molybdenum, nickel,
cobalt, antimony, silver, and
uranium from water; feed lots;
leaching of nitrogen fertilizers
into the groundwater; organically
polluted water; acid mine drainage;
smelter slag; metal contaminated
blast sand; metal plating sludge;
contaminated soils; solidification
and stabilization of hazardous
waste; oil refinery and oil field
sludge; leach residues; batteries,
possibly MTBE (methyl tert-butyl
ether, a gasoline additive) and
various other organic toxins, and
radioactive isotopes, such as
90Sr
and
137Cs.
